Other claims from this paper (9)

Intervention effect Blossom Protect induced systemic acquired resistance PR genes in apple flower hypanthia.
Intervention effect Blossom Protect did not induce induced systemic resistance pathway genes.
Association PR gene induction coincided with increased plant-derived salicylic acid.
Intervention effect E. amylovora inoculation suppressed PR expression in untreated flowers.
Intervention effect Blossom Protect pretreatment offset pathogen immune repression of PR expression.
Intervention effect Blossom Protect pretreatment prevented infection after pathogen inoculation.
Observation PR gene induction occurred two days after Blossom Protect treatment.
Mechanism PR gene induction required direct flower–yeast contact.
Observation Some treated flowers had deterioration of the hypanthium epidermis.
